df1d2f6eb5 Add unchecked variants to Amount and SignedAmount (yancy)
Pull request description:
The checked variants have worse performance than the unchecked variants due to the additional branching operations. To improve performance where overflow is either not possible or not a concern, unchecked variants of `Amount` and `SignedAmount` are introduced for addition, subtraction and multiplication.
Note, it seems the default behavior for the test framework is to panic on overflow, so I haven't figured out a good way to add tests for this. Marking as a draft for now.

1384330029 taproot: add TapNodeHash getter method on TapTree and NodeInfo (conduition)
Pull request description:
Submitting this to fix what I think is an API hole. Please correct me if I'm mistaken here and there is an easier way to do what I'm after.
## Problem
From what I can tell of the existing 0.31.1 API, there doesn't seem to be any way for a consumer to build a taproot tree using `TaprootBuilder` and then simply output the resulting tap tree merkle root `TapNodeHash`.
Instead, the API forces me to do `TaprootBuilder::finalize(secp_ctx, internal_key)` first to get a `TaprootSpendInfo`, and then call `TaprootSpendInfo::merkle_root()` to get the root `TapNodehash`. This requires ECC point addition/multiplication for the tweak operation (inside `TaprootBuilder::finalize`), so it is a lot less performant than the simple hashing operations needed to build a taproot tree.
Obviously if I want to spend the taproot tree, I'll need to tweak an internal key. But if all I want is to examine the merkle root hashes of taproot trees (e.g. for quick validation), there should be a faster and more direct option for me.
## Suggested Solution
My suggestion, demonstrated in this PR, would be to add a couple of simple getter methods:
- `TapTree::node_hash() -> TapNodeHash`
- `NodeInfo::node_hash() -> TapNodeHash`
These rhyme with the existing `LeafNode::node_hash()` method. These provide a roundabout way for downstream consumers to extract a taptree merkle root `TapNodeHash` while still using the safe API provided by `TaprootBuilder`. I would simply use `TaprootBuilder` to build a `TapTree` or `NodeInfo`, and then invoke the `node_hash` method on that object. No point addition required.
## Footguns
This does open up more opportunities for consumers to footgun themselves by, for example, committing a P2TR script pubkey to a leaf node by accident, instead of the root node. I'd argue this possibility already exists in the form of `LeafNode::node_hash()`. We're not making that problem much worse here.
If the caller is using `TaprootBuilder` to construct their tree, the only way they'll be able to get a `NodeInfo` or `TapTree` in the first place would be to finalize the builder into it, which seems like an acceptable and intuitive-enough usage path to me.

Fixes a gap in the API of the taproot module. Callers can now use
TapTree::root_hash or NodeInfo::node_hash to extract the taproot
tree merkle root hash for fast validation without any ECC overhead.

Pull request description:
This test is failing. I do not want to dive back into kani right now, just remove it.
This is what I originally did in #2454 but changed directions and tried to fix it. Running kani test takes ages and I'd need to dig back to refresh my memory to work with kani. I don't have the motivation to do that at the moment. Just remove the test.
FTR I added the test recently without fulling thinking it through and it has never passed so we are not loosing any coverage. Doing this was the original mistake I should not have made.

1d13020129 test: Add conditional check for debug_assertions (yancy)
Pull request description:
Currently running `cargo test --release` blows up because of the tests that panic. This PR adds a conditional check `debug_assertions` which causes those tests to not be run in release mode. Besides fixing `cargo test --release` this PR sets the stage for a larger PR to test arithmetic tests that are `unchecked` (will overflow in release mode instead of panic) started here https://github.com/rust-bitcoin/rust-bitcoin/pull/2436. Also I think we ought to add `cargo test --release` to CI.

Note, we add code to the `impl_write` macro to implement both

d3d5ee1047 Improve error handling in errors emmited by `keys` (harshit933)
Pull request description:
For now I have tried to group those functions which can produce more than one error and changed the functions which were generating single error from `Key::Error` to the respective error. Let me know if this needs to be changed.
Also in `psbt/error.rs` I have changed the `InvalidPublicKey(crate::crypto:🔑:Error)` to `InvalidPublicKey(crate::crypto:🔑:FromSliceError)`. What should be done here?
Changes -
- in `from_slice` changed the `error` to `FromSliceError`.
- in `verify` changed to `secp256k1::Error` as it can return only one error.
- in `from_str` changed to `FromSliceError`.
- in `CompressedPublicKey` changed `verify` from `Error` to `secp236k1::Error` as it only returns one error.
- introduces CompressedPublicKeyError
- Removes impl from `bip32.rs`

In BIP0032, m is used as a variable for the root extended key. It is not
meant to be used as a constant prefix when serializing paths.
Update the DerivationPath parser to no longer require the m prefix.
Remove the m prefix from the unit tests and the bip32, ecdsa-psbt,
and taproot-psbt examples.

343510d3a0 kani: fix Amount overflow test (Andrew Poelstra)
Pull request description:
Our Kani CI job is currently failing. See https://github.com/rust-bitcoin/rust-bitcoin/actions/runs/7770495422/job/21190756253
This fixes one of the issues; the other is that we're hitting a multiplication assertion in the test we added in https://github.com/rust-bitcoin/rust-bitcoin/pull/2393 which I'm unsure how to deal with.
For reference, testing this was a bit of a PITA. I needed to
```
# Ok, these steps are easy/obvious
cargo install kani-verifier
cargo kani
```
This will give you an error located in core/panic.rs or something with the description `This is a placeholder message; Kani doesn't support message formatted at runtime` which is not super helpful. To get the actual failure, you need to write
```
cargo kani --enable-unstable --concrete-playback=inplace
```
which will add a weird unit test which calls into Kani to exercise the original test with a specific input value. Because it calls into Kani you can't just run it with `cargo test`. You need to run
```
RUST_BACKTRACE=1 CARGO_INCREMENTAL=0 cargo kani playback -Z concrete-playback -- kani_concrete_playback_check_div_rem_8626518785677487871
```
where `CARGO_INCREMENTAL=0` disables incremental compilation (this was causing rustc to flame out with a "filename too long" error because it was trying to create some intermediate file with multiple hashes and crate names in it), and the `kani_concrete_playback_123456789` thing is the name of the test that gets added (which you can easily find by reading `git diff`).

Add two public API functions on the two public keys, both called
`p2wpkh_script_code` to do exactly as the name suggests.
Of note, I was not able to find anywhere to use these in example code,
this is because of we always use the new `p2wpkh_signature_hash`
function. The new functions may be useful for a user calling
`segwit_v0_encode_signing_data_to`. The may help document the library as
well.
